Product Details

Supertech Performance brings over 20 years of manufacturing expertise to their engine valve lineup. Developed in close collaboration with professional engine builders, Supertech valves are engineered for high flow rates, exceptional durability, and consistent quality across a wide range of performance applications.

Material Options:

  • Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and reliability. Supertech primarily uses EV8 (21-4N) stainless alloy for both intake and exhaust valves, with additional alloy options and specialized heat treatments available for specific engine requirements.
  • Inconel 751 Nickel-Base Alloy: Designed for exhaust valves operating under extreme heat conditions, such as those found in turbocharged or supercharged applications where standard stainless valves may fall short.

Coating Technologies:

  • Chrome Coating: A widely adopted surface treatment in high-performance valve applications, providing enhanced hardness and wear resistance.
  • Black Nitride Treatment: A hardening process that creates a smoother surface finish than traditional chrome coating, resulting in reduced friction between the valve stem and guide for improved longevity and performance.

Sold individually — per valve. Please order the exact quantity required for your engine build. For example, a 16-valve engine requires a quantity of 16.

I bought an Exedy Organic Clutch at the best price I could find. Shipping was also prompt. Legit dealer, good business.

Great Price!!<br>Fast Shipping!!<br>Would definitely use again....

Great deals at unbeatable prices!

Quick, easy & reliable.

Found a Thule Vertex bike hitch on here for $50 cheaper than amazon. Extremely fast shipping. Definitely recommend purchasing from here.

I was able to find the lowest price on my 4x4 truck battery with free shipping! Beat everybody else by25.

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.

SO HAPPY! I have to admit, I was hesitant because I had never heard of autoplicity and there wasn't item a picture up for the Thule T2 rack I bought, but wow am I happy. Autopliicity had it for $100 less than other sites and the shipper was Amazon prime fast!!! Definitely a happy customer!!!!

I ordered a Thule 9002 Raceway Bike Carrier on Sunday, April 8 and received the product by Fedex on Wednesday, April 11 with just regular shipping. That is fast service. And the price was $43 cheaper than any other site on the internet (including shipping). I haven't had a chance to use the bike carrier yet but it appears to be new and as advertised with no issues as of this writing. I would definitely recommend this retailer for your next purchase.
